To all whom it. may concern:

Be it known that I, OLivER W. JonNs-QN, a citizen of the United States, residing at. Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new,

'roller-s, obliquely disposed with respect to the main feeding direct-ion, and all having their top surfaces in the samelplanc, means for rotating said rollers simultaneously in the sla-ine direction', and an adjustable guide late arranged adjacent to one end of said iied rollers', with its lower edge below theirl top surfaces and with its guiding face par-- allel with the direction in which it is desired receiving machine.

The invention consists of the conibiiiatioii of parts above mentioned, and in various more spccihc combimitions, and sub-combinations of parts, and in certain details of construction which will be hereinafter desciibcd and definitely pointed out in the claims. y

ln the drawingv Figure 1 is a plan view of the improved paper feeding mechanism. Fig. '.Z is a side 4elevation thereof with the driving sprocket. removed. Fig. 3 is a vcrt-ical `sectional view in the plane indicated bythe bentI line 3---3 of Fig. l. Fig. 4 isan elevation ot' the delivery end of the mechanism; and Fig. 5 is a detail showing the manner of supportingr the front ends of those rolls which do not extend to the side bars of the supporting trame.` l

Referring to the parts by letters, A reprtsents a rectangle Yframe capable ot being attachcd to the' receiving machine in such manner thatA it may occupy a substantiallyh horizontal position, out may be swung up out. of the way when not ir. use. The meaiis provided for securing this frame to the re ceiving machine are the following:

driving roll.

Two plates C are pivote'd to the sides` ol' this frame by means of ahiied horizontal 'pivots c. These plates extend beyondthe ront end of the frame and are provided with vertically perforated hinge eyes c', by means of which they mav be piv'otally connected h i' pivot pins f with plates F, which hitter plates ai'e designed to be attached in any suitable way with thc frame of the r. ceiving machine. Locking pinsv c2 are provided and they pass respectively through,

the )lates C into holes in the side frame in em vers when the frame is in n horizontal position, whereby said plate is held in that position; it guide plate B is ailjustablysecured to one of the side frame. members with its froiit'l'acc in a vertical plane, pai'- allel with the direction in which it is desired that the paper sheets shalibe moving when delivered into the receiving machine. This plate is laterally adjustable 'by means of two screws J, "which screw through brackets 1y secured to the side frame 'member and these screws arel provided near their inner 'of the device. 'The rolls at the forward end of the frame are mounted in nea rings secured to one side member and to the front member of the frame; thc rolls at the rear end ol' the frame are mounted in bearing:- secured tothe `other side and to the rear mtinler of said frame; and the intermediate rolls being mounted in hearings on both side members of said frame.

The top ,edges of these rolls are all in the same horizontal plane, which is slightly above the lower edge of said guide. plate. One of the rolls D' placed intermediately of the others (thereby dividing said rolls into two series), is of larger diameter and serves as the driving roll. .In each of the rolls D there is an annular 'groove d,

there being two of such grooves d, d' inthe that those in the forward series of rolls, that These groot-es 'are so placed is to say, the rolls in front of the driving roll,

35 groupe( .f roll of the next pair, and so on.

are all in. the vaine vertical plane with each other and wit-h one of the grooves d in the driving roll, which plane is at right angles tol the axes of said rolls.l The grooves in the 5 rear series of rolls are all of the same vertical plane with each other and withthe other o'roove d mth driving roll, which lane is iikewise at right :ingles to the' axes of t ie rolls.

The. driving roll may be. driven by any .suitable means. For example, it may be -pr0- vided with a beveled gear o" on the nrojecting end of its su )porting triiiiiiioii w iich en# gages Ywith another beveled gear q rotatably mounted on astub shaft secured to one' of the side members of the frame. A. This latter beveled gear is secured upon a sleeve g' to which is also secured a sprocket wheel gz by means of lwhich it may be driven. The .power to drive the sprocket wheel may come '20 troni the. receiving machine -throu h a` sprocket chain g3 indicated b v dotted ines. It is preferable to em loy a tlexible dri-ving member, like a sproclitet chain, because it does notinterfere with swinging the frame A upward ou of t-iie way.

The various rolls D are driven from the .driving roll D by two endless cord belts l, which are respectively wound aboutI the several rolls in ltij-peculiar manner,l as shown in the drawing, which provides suitable traction for the rollsl without applying thereto any unnecessary\` riction. For convenience in describing the iminner in which the cord docs so ass around these rolls, they may he liin pairs. Itwillfbe understood thaithe cordV lies in the groovesd, d referred to, and wholly below thelto surfaces of the rolls. The cord passes over tie`feeding roll D' to the forward roll'of the nextfpair, vthen down lyonder said roll and up over the rear roll of aiound the rear series of rolls.

. A' the front end ofthe franie are two supplementary feed rolls E, E whose axes are at right angles to the guide face of the plate B. These may be driven by a cord belt running over groovedpulleys` e e secured to said rolls respectively, and a (frooved pulley g secured to sleeve g. hen now a sheet of paper is dropped upon' these feed rolls D, D', it will he carried forward toward the receiving uide plate-after. which it willbe moved orward with its edge so in contacthand will therefore be moved` in a direction parallel` with Vsaid oruide face toward the receiving inachine. T esu iplenientary rollers, E E', by which it is tiiial y carried into said receiving machine, have no tendency to move it laterally but only straight forward in the required direction.

As before stated, this vfeeding mechanism is adapted for printing presses, and ruling machines; .and when so use d, it is desirable, and sometimes necessary, that the deliverv of said -sheets shall be accurately timed with respect to'the movementsof the receivinfr machine. To produce this result, hold-bach means ai'e'pro\'irled,-that is to say, means which will check'the advance of the. sheets, and will release them at the proper time with respect to movements of the receivingiiiachine. This hold-back device consists `of a. roch. shaft Hineunted transversely in frame A below the feed'rolls, and a series of arnis h secured to said rock shaft having upwardly turned fingers 7i which may project into the )ath qf the advancing paper sheet 'ust in iront of the front supplementary fee roller E.' This rock shaft may have an arm h to which is attached a forwardly extended link.- '7i-i whose front end ma. f be supported in a ositioii to be engaged by a. cani K. attache t-0` some rotary part of the receiving machine.`

It. may be necessary to ein loy a tightenci 'i for one or hot-h of the corr driving belts. Such a tifflitcner inay he a lever ).I pivoted to an arm which is in turn secured to a transverse bar A. forming a part of the frame A. The l'cvcr may have a 'grooved sheavc m mounted in its end, engaging with the topof the lowei` stretch of the cord loop; and this lever arm may he pulled down b v means` of theliead p on a screw l which screws into said cross bar,said head havingr an annular groove p into which projects the forked cnd of the other arm of said tightenei lever.

lt is sometimes desirable that the feed "frame be not si". ung out of the way on :i hori- '/.ontal axis, but Lthat it be swungr on ay vertical axis while stiil in a horizontal position. 1t",

is for this reason that. thc frame is connected with the bracket plates F on vertical pivots f. Either one of these pivots may be withdrawn and the frame may be swung around upon the other into any desired position.
